reduced testcase
One of testcases for PR45352 fails with -fno-early-inlining:
$ gcc -Os -fselective-scheduling2 -fsel-sched-pipelining -fprofile-generate
-fno-early-inlining pr45352.i
/mnt/svn/gcc-trunk/gcc/testsuite/gcc.dg/pr45352.c: In function 'df_md_alloc':
/mnt/svn/gcc-trunk/gcc/testsuite/gcc.dg/pr45352.c:24:1: internal compiler

The attached more reduced testcase fails the same way:
$ gcc -Os -fselective-scheduling2 -fsel-sched-pipelining -fprofile-generate
-fno-early-inlining pr46521.c
pr46521.c: In function 'df_md_alloc':
pr46521.c:17:1: internal compiler error: in reset_sched_cycles_in_current_ebb,
at sel-sched.c:7092
Please submit a full bug report,

I verified the testcase doesn't give any warnings with -Wall -W.
